To all 'whom it may concern:

Beit known that I, THOMAS F. BURKE, a

citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Freight-Car- Supporting Frames,. of which the following is a specification.

. the several views.

.My invention relates to the supporting frames of freight cars and especially to what are known as gondola cars or transporting coal, broken stone, et c., where-the load is very great, the object being to construct the frame of reinforced channel-beams extend: ing longitudinally of the car and cross-beams so positioned and braced as to give the maximum support compared with the weight of material used in its construction. 7

The construction and advantages of my invention will be explained in detail hereinafter and illustrated drawings in which- Figure 1 is a top plan view of my improved frame, Fig. 2, a bottom plan view, Fig. 3, a cross sectional view on the line ac-x of Fig. 1, and Fig. 4, a longitudinal sectional view of one of the end fragments of the frame on the line y-y.

In the drawings similar reference characters indicate corresponding parts throughout The side sills of my improved car frame consists of channel beams A having secured to'their flat sides a fiat plate of metal A of the same width and length as the beams A, theobjectof this construction being to reinforce the edgewise strength of the commercial channel beams without losing the rigidity imparted by the channel-beam flanges. The beams A and plates A may be secured together by means of bolts or rivets a or other suitable means.

The ends of the sills have secured thereto plates B by means of angle plates 1) and angle beams b. The middleof the sills are braced and strengthened by means of cross-beam C of the I-beam type secured inthe channels of beams A by means of angle plates 0. Intermediate of the end plates B and crossbeam C are cross-braces consisting of beams D secured in the channels of beams A by means of angle plates (1 and having secured to each edge an angle beam E. F indicates triangular plates secured to the plates A and to angle beams E.

G G indicate angle beams reinforced by plates G G connecting each end plateB in the accompanying and cross-brace beam D, the-flangesof the anglebeams G G being turned towards one another.

H H indicate plates secured tochannel beams A by means of angle platesh and having their middle portions cut away as shown at I to receive beams'G and plates G and secured thereto by means of angle plates i, the

upper edges of the plates H being extended upwardly an appreciable distance to support the slanting floor of the car body (not shown).

J J represent other plates secured to channel beams A by'means of angle plates these;

plates being also cut-away as shownat-K to receive beams G and plates G and are secured to plates G by means ofangle platesk;

Lindicates z-shaped plates H and J and M-plates secured to the top flange of each channel beam A and to the inner sides of plates gle plates m.

N indicates plates secured to the top flanges of beams G and at angle plates secured over said plates N and to'the exposed flanges of angle plates'i and 7c.

0 indicates angle cross-beams secured to H'and'J by means of anthe lower edges of plates H and J and having the outer ends of their vertical flanges cut away and the horizontal-flange ends bent upwardly and secured to beams A.

' P indicates a late secured under the middle'portions of eams O. Plates N and P are provided with holes n and p toreceive the king ins (not shown) to attach the wheel true is thereto. It will be apparent that the body bolster comprising plates H and J and their connections including plates M and cross beams braces secured to the lower. flanges of form very efiicient, braced bolsters which support the load with a minimumexpe'nditure of material;

Having thus described my invention what I claim is 1. In a supporting frame for freight cars, side sills extending the full length of the frame, plates connecting the ends of said sills, angle beams secured to saidplates and the sills, cross-braces connecting said sills, longitudinal beams connecting the endplates and braces, and bolster plates secured to said sills and longitudinal beams, substantially as shown and described.

2. In a supporting frame for freight cars, side sills made of reinforced channel beams extending the full length of the frame, plates connecting the ends of said sills, cross-braces connecting said sills intermediate of their side'sills made of channel beams reinforced by plates secured tothe backthereof, lates connecting the ends of said sills, angle eams,

secured to said plates and to the flanges of longitudinal; composite channel beams ,5 angle iron trussgbeamsrsecured to the :lower: plates and to the side sills, and

' necting each end plate, plates connecting the sills having edges of said said sills, a cross-brace connecting the sills between each longitudinal, composite channel beams concross-brace, and they adjacent their middle portionsicut away to receive said plates's'ecured to the top of the longitudinal,

composite channel beams and to the underside of the angle-irontruss beams and hav- 7 ing holes therein to receive the truck king pin,rsubstantiallyas shown and described. 4. In a supporting frame for freight cars,

side sills madeof channel beamsreinforced endand the middle thereof,

by plates secured to the back thereof, lates connectingthe ends of said sills, angle eams said sills, a cross-brace connecting the sills between eachend and the middle thereof,

longitudinal, composite channel beams connecting each cross brace and the adjacent endplate, lates connecting the sills having. 1

their -midd eportions cut away to receive said longitudinal, composite channel beams, ahorizontal the plates aforesaid, the and braced by means'o plate secured to each sill and to lates being secured angle plates, truss beams made of angle-beams secured to the lower edge of said plates and to the side sills, i

a plate secured to said longitudinal, composite channel beams having a hole therein, and

with the hole in above-named tially as" shown and described.

In testimony whereof 1 hereto aflix my," signature in the presence of two witnesses.v
